There's a lot of talking about the proper use of the disavow tool. One of the trickiest situations: So you have a new client sign-up, you research the links and see this client has quite a shady past, what do you do? The client isn't hit by anything yet but he/she may be hit in the future (and he/she will probably even blame you for that as it "used to be fine")
Is it a smart decision to do preemptive disavow?
Chuck Price over at SW recommends disavowing *only* if you are sure you need to. Matt once said to use it only after link removing ("only after there is a "small fraction" of links left to remove"); later Matt asks to use the tool more aggressively ("disavow domains")
@Marie_Haynes says she tried doing "preemptive penguin disavow" and saw a decline in traffic (but maybe for other reasons...)
What are your thoughts?
